Foster care for pets is a way for people to care for pets who might otherwise be put down.  The people who are the gatekeepers might love animals, but one wonders if they know how to read fellow humans.  I've heard several word-of-mouth stories about people applying to be foster pet owners but the process is so painstaking that they back out.  The most recent one was that a Labrador Retriever was not allowed to stay with someone who had a swimming pool in the back yard because the pet might drown.  I've never heard of a Lab that can't swim.  So, rather than have a loving family, he gets to go back to four walls, and maybe worse.
